So, you've decided to use npm to publish your project.
Fantastic!
There are a few things that you need to do above the simple steps that your users will do to install your program.
These are man pages. If you install npm, you should be able to
then do man npm-thing
to get the documentation on a particular
topic.
Any time you see "see npm-whatever(1)", you can do man npm-whatever
to get at the docs.
You need to have a package.json
file in the root of your project.
See npm-json(1) for details about what goes in that file. At the very least, you need:
-
name: This should be a string that identifies your project. Please do not use the name to specify that it runs on node, or is in JavaScript. You can use the "engines" field to explicitly state the versions of node (or whatever else) that your program requires, and it's pretty well assumed that it's javascript.
It does not necessarily need to match your github repository name.
So,
node-foo
andbar-js
are bad names.foo
orbar
are better. -
version: A semver-compatible version.
-
engines: Specify the versions of node (or whatever else) that your program runs on. The node API changes a lot, and there may be bugs or new functionality that you depend on. Be explicit.
-
author: Take some credit.
-
scripts: If you have a special compilation or installation script, then you should put it in the
scripts
hash. See npm-scripts(1). -
main: If you have a single module that serves as the entry point to your program (like what the "foo" package gives you at require("foo")), then you need to specify that in the "main" field.
This is important.
If you can not install it locally, you'll have problems trying to publish it. Or, worse yet, you'll be able to publish it, but you'll be publishing a broken or pointless package. So don't do that.
In the root of your package, do this:
npm install .
That'll show you that it's working. If you'd rather just create a symlink package that points to your working directory, then do this:
npm link .
Use npm ls installed
to see if it's there.
Then go into the node-repl, and try using require() to bring in your module's main and libs things. Assuming that you have a package like this:
node_foo/
lib/
foo.js
bar.js
and you define your package.json with this in it:
{ "name" : "foo"
, "directories" : { "lib" : "./lib" }
, "main" : "./lib/foo"
}
then you'd want to make sure that require("foo") and require("foo/bar") both work and bring in the appropriate modules.
npm will stubbornly refuse to expose your password in the clear. That
means that you'll have to install whatever package provides openssl.h
on your system. When you ./configure
node, make sure that it says:
Checking for openssl : yes
Create a user with the adduser command. It works like this:
npm adduser bob password bob@email.com
This is documented better in npm-adduser(1). So do this to get the details:
man npm-adduser
This part's easy.
npm publish /path/to/my-package
You can give publish a url to a tarball, or a filename of a tarball, or a path to a folder. (Paths have to either be "." or contain a "/".)
This makes it easier to install without your users having to know the version ahead of time.
npm tag my-package@1.2.3 stable
You can also use other tags, but "stable" and "latest" have reserved meanings.
Send emails, write blogs, blab in IRC.
Tell the world how easy it is to install your program!
